Other notes: If you choose to use a darker color (such as Charrua) as the MC on this bag, don't forget that darker-colored yarns felt more (and faster!) than lighter-colored yarns. I actually did forget that little nugget of information, and when I pulled it out from the completed wash cycle, was surprised at how much more this version had felted! (Also, you should check on it from time to time as it's undergoing the felting process - that was tactical error #2 for me, leaving it to its own devices)
